Study finds visual acuity improves immediately after Opti-K

PHOENIX – Researchers reported in a poster here at the American Academy of Optometry annual meeting that a new laser treatment for hyperopia and presbyopia resulted in improved acuity 10 minutes after the procedure.
Uncorrected distance and near visual acuity improved in 13 of 14 patients studied, reported Sherry L. Audycki, OD, BS, FAAO, and Robert Audycki, OD, Dartmouth, Mass.
The researchers described Opti-K (NTK Enterprises) as a noninvasive, fast, repeatable refractive laser treatment that reshapes the cornea without significant healing time.
This study was a single-arm, nonrandomized, unmasked clinical investigation of 14 patients with hyperopia and presbyopia between 42 and 73 years old, with a mean age of 58.6 years. Pretreatment uncorrected binocular distance visual acuity ranged from 20/20 to 20/64, and pretreatment uncorrected binocular near visual acuity ranged from 20/40 to 20/160, they reported.
After treatment, binocular uncorrected distance visual acuity ranged from 20/20 to 20/60, with 13 of 14 patients 20/32 or better. Binocular uncorrected near visual acuity ranged from 20/25 to 20/63, with 13 of 14 patients 20/40 or better.
Postoperative refraction data was not available.
“This is a safe, noninvasive, repeatable treatment option for hyperopia/presbyopia, giving patients immediate uncorrected distance and near visual acuity improvement,” the authors concluded. – by Nancy Hemphill, ELS
